SPEGIFIG ATION forming part of Letters Patent No. 228,441, dated June 8, 1880.

' Application filed July 1, 1879.

To all whom it may concern:

Be it known that I, AUGUST BUERMANN, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Spurs, of which the following is a specification.

Figure 1 is a side view of a spur to which my improvement has been applied. Fig. 2 is a top view of the same. Fig. 3 is a detail perspective view of the rowel-holder.

Similar letters of reference indicate correspondin g parts.

The object of this invention is to furnish spurs which shall be simple in construction, inexpensive in manufacture, light, strong, durable in use, and neat in appearance.

The inven tion consists in forming the rowelholding portion of the spur of a single piece of sheet metal, the parts forming the rowelarms being cut out and bent toward each other in position to hold the rowel, and two sections, partially cut from the said arms, being bent to set against the heel portion of the band, so that said sections may be riveted thereto.

A represents the heel-band, B the rowelholder, and G the rowel, of a spur. The heelband A is made in the usual way, and may be plain or ornamented, as may be desired. The rowel-holder Bis made of sheet metal out out into the proper form and bent into the proper shape with suitably-shaped cutters and dies. The end parts of the cut-out piece of sheet metal are bent up parallel with each other to form a space or slot to receive the rowel O. The middle of the end parts of the holder B is cut away to make the said holder lighter, ears I) being left upon each side of its bend to receive the rivets by which the said rowel-holder is secured to the heel-band A. Sufficient material must be left at the ends of the holder B to give a substantial support to the pivot of the rowel C, as shown in Figs. 1 and 3. The rowel O is cut out in circular form with teeth 0 upon its edges.

1n the body of the rowel 0, between its teeth and pivot hole or center, are formed openings 0 which may be made in semielliptic form, as shown in Fig. 1, or in semicircular form, or in triangular form, or in the form of squares or diamonds, or of any other desired form. The openings 0 give a better ring to the rowel when it strikes against the holder B. The openings 0 also give an appearance of lightness to the rowel without materially affecting its strength.

Having thus fully described my invention, I claim as new and desire to secure by'Letters Patent- The rowel-arms formed of one piece of sheet metal and bent backward, as shown, to hold the rowel, and the ears I), cut from the rowelarms and bent forward to a line with the heelband A, substantially as set forth.

" AUGUST BUERMANN.
